Hej vaibhav! Assuming you use the official Ubuntu packages:
> mpicc: error while loading shared libraries: libopen-pal.so.0: cannot > open shared object file: No such file or dir The library should exist under /usr/lib/libopen-pal.so.0 (which symlinks to /usr/lib/libopen-pal.so.0.0.0 which symlinks to the real position /usr/lib/openmpi/lib/libopen-pal.so.0.0.0). Is it there? If not, then you need to install the openMPI shared libraries (the package is called libopenmpi1). Best regards Fabian
